LINING- FOR TOBACCO-PIPES.

Be it known that I, HARRY L. CANFIELD,

a citizen of the United States, residing at Homer, in the county of Winona and State of Minnesota, have invented new and useful Improvements in Linings for Tobacco-Pipes, of which the following is a specification.

This invention relates to improvements in linings for tobacco pipes and it proposes as a new article of manufacture and sale a lining shaped to fit the stummel of the pipe and having for its purpose to artificially and favorably affect the flavor or taste of the smoke.

It is well known to smokers that all 1 pipes regardless of their character are unthis crust becomes .of onlya very 85 .surface or in a draft.

satisfactory when new or first used in that the flavor of the smoke is detrimentally affected by the mate'rial of the stummel and the smoke is very hot as it enters the mouth, causing an unpleasant dryness and burning or biting of the tongue and'the roof of the mouth. Ultimately, when the pipe has been broken in, this objection is overcome or substantially minimized by reason of the fact that a crust or deposit of tobacco tar gradually forms upon and fadheres to the inner surface of the stummel and preventsthe flavor of the smoke from beingafiected by the material of the stummel and also rapidly absorbs heat from the smoke, and, hence, cools the same. In time so thickthat it allows small quantity of tobacbo as a-charge for thepipe. Thereupon, the

.crust mustbe removed and this is accomplished by cutting it from the stummel, an operation. which is usually carelessly performed and is quite liable to injure the pipe. If the crust is wholly removed or cut to an extreme thinness, ing conditions obtaining when the pipe was new are in large measure present again and do not disappear until anew crust has suificiently formed. In other words, when thecrust is removed, the pipe must be again broken-in just as in the case of a new pipe. Another objection to the use of a new pipe, e. 9., a pipe wlthout any internal crust or deposit, is that its stummel becomes highly heated in a very short time and if the pipe is smoked. too fast the stummel, if of briar, may become burned, and if of meerschaum, may become baked and cracked, especially if, when hot, it is laid on a cool The crust or deposit Specification of Letters Patent.

which ultimately forms is a substantial proany appreciable heating thereof.

he object of the present invention is to provide a lining which may be readily fitted 1n the stummel of a pipeand which not only prevents the flavor of the smoke from being afi'ected by the material of the stummel, but, in fact, improves such flavor, which readily stummel as soon as the pipe is first used; which protects the stummel against heating; and which may be readily removed 'whenever the occasion may require without danger of injury to the pipe and as readily'fitted in old pipes as in new ones. In other words, the lining ent invention secures al the advantages of the crust or cake which ultimately forms in a pipe, being,'in fact, an artificial substitute therefor but avoids the disadvantages of such crust or cake since it makes the use of the pipe satisfactory from the outset and may be removed without endangering the stummel.

With the objects above stated in view, the invention comprises a tubular lining of compressed. cured tobacco having incorporated therein a palatable artificial flavoring agent such as licorice and preferably, though not necessarily, having its outer. surface coated with a thin film of an adhesive substance which promotes its adherence to the pipe. This substance may advantageously be the same as the flavoring agent, e. 9., licorice.

The improved linings will constitute unitary articles of manufacture and sale and will be made to fit pipe stummels of various diameters. In using the lining, its outer surface, preferably coated with licorice, is first moistened, and the lining is then fitted in the stummel, adhering to the surface thereof and with its upper end flush with the edge of the stummel and its lower end above the bore in the stem. The lining quickly chars, after smoking, but being strongly compressed is not readily combustible'and, therefore, has a long eflicient life. The charring of the 'li ning resembles the natural char in an ordlnary pipe and the heat developed by smoking causes the licorice toact as a cement in firmly binding the lining to the stummel. The licorice which is incorporated in the lining while incidentally favoring the. quality and aroma of the smoke is primarily abinder and predangering the pipe,

binders may be used, the only requirement being the selection of a binder which is palatable and will not unfavorably affect the aroma of the smoke.

The lining may be very readily adjusted to fit a particular pipe since it has a measure of flexibility and can be trimmed with a pen knife. smoked so that the lining is charred, the lining resembles the ordinary crust and, hence, its presence, as an artificial adjunct, is not noticeable. The lower end of the lining is in a plane above the bore of the stem and an enlarged cavity is thus provided at the lower end of the stummehjust as in the case of the ordinary crust, in which the smoke is cooled in its passage through the pipe. When the occasion requires, the lining can be readily removed from the stummel by using a knife, without, however, en-

since the lining does not have the flint-like hardness of the ordinary crust nor as strong an adhesion to the surface of the stummel.

When an old lining is removed anew one may be conveniently substituted and substitutions of linings may be made throughout the life of the pipe. The linings may be used in connection with pipes of various character and in connection with false composition or meerschaum bowls which are used in the so-called sanitary pipes and as protectors for meerschaum pipes. The invention is illustrated in panying drawing in which: 'Figure 1 is a vertical sectional view showing the lining fitted in the stummel of a. pipe. Fig. 2 is a horizontal sectional view on the line 2-2 of Fig. 1.

Similar characters of reference designate corresponding parts in both of the views.

The lining consists of a cylindrical tubular body 1 of strongly compressed cured tobacco impregnated with a palatable binding agent, preferably licorice, and also preferably externally coated as at 2 with a palathe accomtable cementing agent, also licorice, the coating being in the form of a thin film which covers the cylindrical outer surface of the lining and also and preferably its upper end. The lining is fitted snuglyin the stummel A and adheres thereto, its upper end being flush with the upper edge of the stummel and its lower end being in a plane above the bore of the stem, thus providing an enlarged cavity 3 at the lower end of the stummel in through the pipe. 1

By the use of the lining, the unpleasant eifects of smoking incident to the use of a When the pipe has been once nesses. which the smoke cools during its passage i new pipe are avoided, the lining at the outset of the use of the pipe securing the advantages of the ordinary crust which requires considerable time for its suflicient formation.
